<h2>\addtolength</h2>


<p><tt>\addtolength{len-cmd}{len}</tt></p>


<p>The <tt>\addtolength</tt> command increments a

    <a href="ltx-86.html#lencmd">length command</a>,

    <tt>len-cmd</tt>, which is specified by the first argument,

    by the amount specified in the <tt>len</tt> argument. It can

    be a negative amount.</p>


<p>As an example,</p>



<pre>

    \addtolength{<a href="parskip.html">\parskip</a>}{-.1\parskip}

</pre>


<p>decreases the value of <tt>\parskip</tt> by 10%.</p>
